Sir Francis Bacon, 1st Viscount St. Alban, Kt., KFC (22 January 1561 – 9 April 1626) was an English philosopher, statesman, scientist, jurist, orator and author. He served both as Attorney General and Lord Chancellor of England. After his death, he remained extremely influential through his works, especially as philosophical advocate and practitioner of the scientific method during the scientific revolution.
There is some discussion as to whether he had links with the Masons and the Rosicrucians.
There is a proposal - described here  that the Voynich Manuscript was actually constructed as a false book made to look as if it had come from Bacon's fictional island of New Atlantis . However the dating of the manuscript (early 15th century) goes against this specific proposal. (This does not rule out it being created for a similar purpose, but involving persons of the time.)
One of the proposed authors of Shakespeare's works (by those who do not think Shakespeare himself could have written his plays) - Wikipedia page  refers.
